How Many Earths Will We Need if Everyone on Earth Live Like You?

According to this calculator, the avarage result of people in North America is 5 earths.
That of people in China is 2.1 earths. People in South Africa, 2 earths. People in Brazil, 1.8 earths.

It seems that many people's result cannot be less than 1 earth.
We only have 1 earth to live on. It is clear that we need to make change about our lifestyle.

One thing we can do is to think about what to eat.

When comparing "vegan," "meat daily," "balanced meat" and "vegetarian," the result became like this.

If you choose "meat daily," you will need about 1.9 more earths comparing to when you choose "vegan."
If you choose "balanced meat," you will need about 1.2-1.3 more earths comparing to when you choose "vegan."
If you choose "vegetarian," you will need about 0.3-0.4 more earths comparing to when you choose "vegan."

We can see that what we eat effect how much resource we use.
Even if you think it's difficult to go vegan, trying Meat Free Monday or trying to reduce livestock prodcts consumption will make change.
